This invention relates to hair cloth and like looms, and the principal object of the invention is to materially simplify and improve the present forms of this type of loom.

A more specific object of the invention is to provide a novel and materially improved means for taking and retaining the hair in the shuttle which makes possible a substantial reduction in the working parts of the loom and also a material saving in hair by reason of a capacity for utilizing greater proportion of the length of the individual strands.

Still another advantageous feature of the invention resides in the provision of means for automatically interrupting operation of the associated parts of the machinery if the shuttle fails to take up a hair at either end of its travel, and for automatically continuing said operation when the shuttle functions '0 properly.

A still further object of the invention is to pro. ide means operative automatically in the event of the shuttle failing to take up a hair, for preserving the predetermined design intact, this means involving a temporary interruption in the operation of the jacquard mechanism and discontinuance of the hair take-up mechanism until such time as it func tions properly at the position in which it originally missed. In this connection, the lcoinis particularly well adapted for multi color work; since, with the aforesaid. automatic means, when a hair of one color is missed, the hair take-up me: ianism remains inoperative until a hair of the same color missed has been taken hold of by the shuttle.

The invention further involves the provision of novel means for interrupting the loom ope ation in the event of defective or incomplete shuttle action.

The above and other advantageous ends I have accomplished by means of mechanism illustrated in the attached drawings, in which:

Nith reference to the drawings, the machine comprises the usual construction as regards the main frame 1, the lay 2 and the reed 3 carried by the lay in the usual manner. The machine also comprises the usual takeup mechanism including the roll d and the roll 5 upon which the woven fabric is wound. The lay 2 is pivotally mounted in the standard fashion upon a shaft 6, and carries a tainer regardless of their number.

picker stick 7 which is actuated in the usual manner to throw the shuttle across the warp. Since in the majority of the parts forming a part of the present invention the mechanism is duplicated at opposite sides of the machine, I have shown for the purpose of illustration but one end of the machine, the opposite end of the machine being shown, however, in Fig. 17 for the purpose of illustrating details of the automatic stop for the take-up mechanism.

Supported on a transverse arm 8 projecting outwardly from the end of the frame 1 is an upright container 9 for hairs orthe like K which form the weft of the woven fabric.

The container 9 is in the form of an elongated channel and is slidably supported at the bottom upon a track or guide 11. The connection between the arm 8 and the container also is a slidable one to permit a transverse movement of the container longitudinally of the arm. As shown in Fig. 3, the container carries a depending member 12 which slidably embraces the arm 8, the depending member 12 being dovetailed for reception of the correspondingly shaped outer end of the arm.

As indicated. in Fig. 2, the hairs 13 extend longitudinally of the container, and the upper ends of the hairs are exposed on that side adjacent the lay for a purpose hereinafter described. Means is provided also in the form of an adjustable plate 14 in the container at the back of the body of hairs for retaining the hairs at the top in the front of the con- In the present instance, the back of the container carries supports or guides 15 for a pair of plungers 16 which bear against the back of the plate 14, as well shown in Fig. 2, and these plungers are continually forced inwardly of the container by means of a weight 17, see Figs. 2 and 3, on an arm 18 pivoted at 19 to the back of the container 9 and connected intermediate its ends at the point designated by the reference numeral 21 to a block which connects with the outer ends of the plungers 16, 16. Obviously the pressure exerted at the back of the plate 14 tending to press the upper ends of the hairs in the container toward the open front of the latter may be regulated by adjusting the weight 17 upon the arm 18.

In order to reciprocate the container 9 transversely on the track 11 and longitudinally of the supporting arm 8, I provide a cam 22 carried by a ratchet wheel 23 mounted on a stud 24 on the arm 8 and provide means I also for rotating the wheel 23 through a pawl 25 upon a lever 26 also pivoted upon the stud 24 and connected through a connecting rod 27 with an arm 28 upon the rock shaft 6 which carries the lay. The cam 22 is connected with the container 9 by means of a connecting rod or -bar 29 which carries at one end av roller 31 engaging in the cam groove and which at the other end is'conn'ected by means of a bolt 32 with the container 9, the bolt extending through a slot 33 in the end of the arm 8. The connecting rod 29 is also supported intermediate its ends by the stud 24 which projects through a longitudinal slot 34 in the connecting rod. WVith this arrangement, it will be noted that with each stroke of the lay and the corresponding rocking of the shaft 6, the cam 22 is ail'orded a slight rotational movement which results in acorresponding slight movement upon its guides of the container 9, the container being reeiprocated in these small intermittent movements in a path corresponding to the width of the exposed face of the container.

In this loom, the shuttle 35 is adapted to travel in a continuous movement from a position of rest at one side of the lay to a position of rest at the opposite side, and in Fig. 2, I have shown this shuttle in one of the extreme positions with its outer end resting against the picker stick 7. The shuttle employed with this machine is of special construction and is illustrated in Figs. 8 to 13, inclusive. The shuttle carries'a pair of relatively movable elements 37 and 38, which elements project in the present instance beyond the face of the shuttle. The element 37 in that form of the device illustrated in Figs. "8 to 11, inclusive, is fixed in the shuttle, while the element 38 is movable, being pivotally mounted at 39, and this element 38 is curved so that in a normal position the outer end thereof rests against the extremity of the element 37. To normally retain it in this contacting position, I provide a spring 41 which is secured at 42 to the inner end of the element 38 and at 43 to the body of the shuttle. The arrangement provides for a movement of the element 38 on its pivot and against the tension of the spring 41 away from the element 37, as shown in Fig. 11, and in order to effect this movement of the element 38, I provide an operating lever 44 pivoted to the shuttle at 45 and having near that end which engages the element 38'an aperture 46 through which the element 37 projects. In this manner, the lever 4 is made to engage the inner surface of the element 38, and when the opposite end thereof is depressed by pressure exerted on the projecting portion 47, the element 38 is shifted, as shown in Fig. 11, so that the extremity thereof is moved away fromthe end of the element 37. A spring 48 is .provided beneath the opposite'end of the lever 44 which resiliently retains the lever in the position shown in Fig. 10, in which the element 38 is permitted to engage the element 37 As shown in Figs. 8 and 9, the shuttle is provided. with two of these devices, one at ach end, and by reference to Fig. 2, it will be noted that when the shuttle is in the position of rest at the end of the reed, one or other of the pairs of elements 3738 is located directly opposite the container 9, so that when the lay is advanced. into the beat-up position, the ends of the elements 37 and 38 are pressed into the body of hairs in the container at their exposed upper ends. The element 37 which at its extremity is carried to a comparatively fine point is delicately notched at the extremity whereby a single hair may be retained in the notch by the element 38 when the latter presses against the end of the element 87, as previously described, and means is provided. whereby when the ele ments are advanced into the body of hairs within the container, the elements are separated, shown in Fig. 11, and are closed prior to their being withdrawn whereby a single hair will be held clamped between the elements and will be withdrawn from the container as the shuttle moves across the warp. It will be noted that by reason of th continuous intermittent transverse reciprocatory movement of the container 9, the elements 3'? and 38 will he introduced at different points into the container whereby the hairs are withdrawn from the container at a uniform rate across the entire exposed face thereof.

it will further be noted by reference to Fig. 12 that the device constituted by the elements 3? anc 3S and lever i l may be modilied, with the element 38 constituting the relatively lined part and the element 37 being movable with respect thereto. In the form shown in Fig. 12, the elenient 37 is mounted directly upon the lever let, the pivot 45' being outwardly of the projection l? so that the force exerted upon the projection moves the elen'ient 3'1" inwardly of the shuttle away from the element 38" and against the tension oi? the spring 48 underlying the lever is. So far as the elements 3'? and 38 are concerned, they may vary widely, and there is to be no limitation as to their relative move ments or to the method of operating them.

The mechanism for operating the aforedescribed aarts of the shuttle so that the shuttle will pick up the hairs and carry them across the warp is best shown in Figs. 6, i l and 15. lVhen the lay advances into the beatup position with the shuttle in either of the extreme positions, the projecting part of the lever n upon the shuttle engages a spring-pressed plunger 51 mounted in the main frame, the end of this plunger projecting in the path of the projecting portion 4-7 and being normally retained in this advanced position by the spring 52. The tension of this spring is suliicient to overcome the tension of the spring 48 in the shuttle so that the lever 44 when it contacts with the plunger 51 is actuated to separate the elements 37 and 38, described. hen the lever has been forced open to the maximum extent, however, the continued advance movement of the lay forces the plunger 51 inwardly against the spring 52, and this continues until the ends of the elements 37 and 38 are in the body of hairs in the container 9. At this point a projecting arm 58 upon the lay engages a lever 54: pivoted at F5 on the main frame, and the upper end of the lever 54: which carries an adjusting bolt- 56 is adapted to exert a pressure he hind an arm 57 on the inner end of the plunger 51. By reason of the fact that the upper end of the lever 5 iadvances under the action of the arm 53 upon the lay faster than does the lay itself, the arm 51 is carried away from the projection at? of the lever it on the shuttle, so that the elements 37 and 38 are permitted to come together or return to their normal contacting positions while the extremities of these elements are in tl e body of ha rs within the container 9. As a result of this return of the elements into contact, a single hair is gripped between the elements, and when the lay is retracted and the shuttle moves across the warp, the hair is ithdrawn irom the container and carried into place in the shed. In order to prevent a return of the plunger 51 into contact with the projection +1? on the lever 4% before the shuttle is withdrawn in the retractive movement of the lay, with th result that the hair held by the eleits 38 would be dropped, I provide or and a latch 58 pivoted at 59 on the frame adjacent the rear end of the plunger 51, and this latch 58 is provided with a spring 61 which is connected to the trams and which tends continuously to exert a pressure tending to move the upper end of the latch 58 inwardly to the plunger 51, see Fig. 15. lVhen, ther ore, the plunger is carried baci: by the acti n of the lever 5%, as previously described, the latch 58 is carried by the spring to a position in advance of the arm 57, with the result that the plun er cannot be returned to normal position until the latch 58 has been withdrawn. The plun er accordin ly stays in the extreme retracted position until the lay with the shuttle has moved away sullicientiy far into the retracted position that the lever on the shuttle cannot be by the plunger 51 even when the latter is in the advanced position. In order thereafter to tract the latch to again permit the a to move under the action of the springinto advanced position, I provide the latch with a depending rod 62, the lower end of which passes through an aperture in the outer or free end of the lever 26 which actuates the cam 22 and which connected through the rod 2'? with the rock shaft (5 which carries the lay. The arrangement is such that when the lay is moved back to a given extent, the lever 26 engages the adjustable nuts 63, see Fig. 16, at the lower end of the rod 62 and moves this rod downward, thereby retracting the latch 58 and permitting the plunger 51 to return to its advance position preparatory to again actuating the elements 37 and lit) 88 of the shuttle when the lay again moves into the advanced position.

It will be noted that the projections 47 of the levers 4st at the respective ends of the shuttle are positioned so as to lie in different horizontal planes, see Fig. 8, and the levers ist are actuated to release the hairs which havepreviously been carried across the warps by means of a lug 64 positioned one at each side of the machine and respectively in the paths of the projections 47 so that as the shuttle moves into either of the extreme positions on either side of the machine, the projection l7 of that lever 44 connected with the hair retaining device 37-38 which then carries the hair engages the lug at the proper point in the movement of the shuttle to release the hair in the shed.

The usual safety devices are included in this machine which operate automatically to interrupt operation of the machine or parts thereof in the event for example that the shuttle is not thrown completely across the warp and lies in the shed as the lay advances. For the purpose of interrupting the machine under these conditions, the lay carries a horizontally pivoted arm pivoted at (it; on the lay and so positioned that the concaved outer side is held in the path of the shuttle by a spring 7 O as the shuttle approaches the end position. hen, therefore, the shuttle is in the extreme position as shown in Fig. 2, the lever 65 is pressed forward so that its end engages an arm 67 secured to the end of a rock shaft 68. This shaft carries a projecting element or arm 69, see Figs. 2 and (3, which in a predetermined position and with the advance movement of the lay is adapted to engage suitable trip mechanism (not shown) for interrupting the operation of the loom. When the lever is advanced by the shuttle, as shown in Fig. 2, so as to engage the arm (37, the shaft 8 slightly rocked thereby so that the arm 69 is depressed and does not engage the trip mechanism. When, however, the shuttle fails to move into its proper extremeposition in any movement across the warp, the arm 67 fails to advance and to rock the shaft 68, so that the arm 69 remains in a position to engage the trip mechanism, and accordingly as the lay advances, its operation is interrupted and damage to the warp averted.

..t will be noted that the lovers 65 on the opposite sides of the lay operate in conjunction with the same shaft 68 so that with the shuttle operating normally, one or other of the arms 65 is always in a position to rock the shaft 68 so as to carry the arm 69 into an inoperative position.

In addition, I provide the machine a plunger or longitudinally in a guid so as to be engaged at its 1' at each side of slide 71 movable e 72 and arranged ear end by the shuttle when the lay is advancing and in the event that the shuttle has failed to complete its travel. The forward end of the slide 71 engages an arm 73 upon a rock shaft 74, which latter, by means well understood and therefore not illustrated, is operatively 'con nected with the actuating mechanism and controls the operation. of the loom. lVhen the shaft is roclzechas by the means described above, the entire operation of the loom is interrupted.

Means alsois provided for interrupting the normal operation of the machine in the event that the elements -37'38 on the shuttle fail to grip a hair in the container '9. This device consists of a roller or smootlrfaced roll 75 fixed to the lay in a position such that a hair held by the shuttle will be drawn over said roll 75 as the shuttle moves towards the opposite side of the mach-inc. The device further comprises a second roller or smoothit'aced arm 76 which is held in an upright poition adjacent the arm 75 by an arm 77 at 9d a sleeve 78 rotatably mounted upon a pin 79 held between two lugs 81.81 on the lay. The sleeve 78 carries a pin 82 engaged by the outer end of an arm 83 which is pivotally mounted at 84 to a fixed part of the and which has an extension 85 carrying 313, {H apted to be engaged by an element is; on the arm 3:) when the latter arm is in the advanced position, as shown in Figs. 4 and 5, the arm 83 being held thereby in a retracted position permitting the arm 76 to lie over towards the body of the lay and in position to be engaged by a hair carried away from'the container at that side of the machine by the shuttle as the latter moves towards the other side of the machine, and the weight of the arm 76 and the associated parts is such that by this contact with the hair the arm 7 6 is swun forwardly away from the lay and into a position in which an arm on the sleeve 7 S-engages a depending arm 89 pivotally suspended at 91 from the lay to withdraw said arm to a position indicated in dotted lines in Fig. 4. This arm 80 also is held in the position retracting the arm 89 when the arm 65 is in the position which it normally assumes under the action of the spring 70 when not engaged by the shuttle. Under thes circumstances, the part 88 being withdrawn from the pin 86, the extension of the lever 83 is retracted by a spring 87 connected therewith whereby the arm 83 is advanced into-engagement with the pin 82 whereby the arm 76 is carried from its normal position away from the body'o'f the lay while the arm 80 is moved towards the lay whereby through the cam action of its inclined extremity it carries the arm 89 into the retracted position shown in dotted lines in Fig. 4. This arm 89 in the normal position which it assumes by gravity and in which it is shown in Fig. 4: lies in a position to engage a shoulder 93 on a rod 94 when the lay is retracted, thereby moving the rod longitudinally in the direction of the arrow in Fig. 5 and rocking a shaft 95 journaled in the frame of the machine and connected with the rod 94 by means of an arm 96, see Figs. 4 and 4.

As shown. in F 4", the rod is n. tched on the under side at 97, and when this rod is shifted as described by the arm 89, the notch 97 interlocks with a shoulder on the frame whereby the rod is held in the retracted position. A spring 99 exerts a downward pull upon the rod 94 and tends to hold the notch and shoulder 98 in inter locking engagement and the shaft 95 in the rocked position. The parts accordingly remain as indicated until released by means hereinafter described.

The opposite end of the shaft 95, see Fig. 17, carries an arm 101 which is adapted to engage the upper end of a pawl 102, which through a ratchet wheel 103 and a suitable train of gears aotuates the take-up roll 4, pivoted below the shaft 95 upon the stud 105. When, therefore, the shaft 95 is rocked by movement of the rod 94 under the action of the arm 89 as previously described, the arm 101 engaging the top of the pawl moves the pawl around its pivot and elevates it out of contact with the ratchet wheel 103, thereby interrupting the intermittent rotation of the take-up roll 4. The arm 101 is sufficiently heavy to rock the shaft 95 to return the parts to the normal position when the rod 94 is released. I

In Jacquard looms, it is desirable, in order to preserve the design intact when the shuttle fails to take up a hair at either end of its stroke, to interrupt the operation of the jacquard mechanism until the shuttle has returned and taken up the hair at that end of the stroke at which it originally missed. Also it is necessary, in order to accomplish the desired result, to prevent the shuttle from taking up a hair at the opposite side of the loom from where it originally failed in the pick-up operation. I accordingly have provided mechanism whereby if the shuttle misses a hair in one position, it is prevented from taking up a hair at the opposite end of the stroke or until it returns and picks up a hair in the position in which it originally failed, and I further have provided mechanism whereby after the shuttle fails to take up a hair, the jacquard mechanism remains inoperative and stationary until the shuttle has returned and taken up the hair at the original position.

\Vith particular reference to Figures 4 to 7, it will be noted that the aforedescribed mechanism whereby the normal operation of the machine is interrupted when the shut-- tle fails to take up a hair is duplicated at the opposite ends of the machine. The shaft 95 accordingly is operatively connected at each end with one of the rods 94 previously described. Also as described, each of these rods is notched on the under side at 97, and when either rod is shifted by the coopn. 89, the notch 9'? interlocks with or 98 on the frame whereby the rod -n the retracted position. By reason of their connection with the common shaft when either one of the rods 94 is shifted as described, the other will be corresponding ly moved, and is accordingly necessary to nroviue means whereby only the rod which is actually operated upon by its cooperating arm 89 will lock with the shoulder 98, the other being free to return to its normal position. This I accomplish by means of a bell crank lever 106 pivotally secured at 107 to the frame in such manner that one end 108 of the bell crank lever in a normal position lies against the shoulder 98 in such manner as to render this shoulder inoperative to catch the corresponding shoulder formed by the recess 97 of the rod 94, the end 108 of the lever 106 being sufliciently wide to prevent the forward end of the recess 97 from passing over the rear edge thereof in the rearward movement of the rod 94. A spring 109 connected with the lever 106 and with the frame normally retains the lever in the aforesaid normal position in which the end 108 of the lever renders the shoul der 98 inoperative. This spring 109 is sufliciently strong to entirely counteract the effect of the spring 99 on the rod 94.

t will he noted, however, that when the depending arm 89 on the lay engages the shoulder 93 on the rod 94 to carry the rod rearwardly as described above, there is a natural tendency by reason of the arcuate move ment of the lay to carry the outer free end of the rod 94 downwardly, and this downward force in conjunction with the force exerted by the spring 99 is sufficient to depress the end 108 of the lever 106 against the tension of the spring 109 so that the shoulder 98 becomes operative in the recess 97 to hold the rod 94 in the retracted position. It will be noted that the shoulder 93 is inclined to the perpendicular to accord with the inclination of the arm 89, as well shown in Fig. 7, which increases the tendency of the contact to depress the outer end of the rod 94 as described.

That one of the levers 94 therefore which is at that side of the machine at which the shuttl originally misses the hair, is looked as described, whereas the other remains free to return when the first said lever is released.

At each end of the shaft 95 I also provide an arm 111 which normally occupies the position as shown in full lines in Fig. 7 and which, when the rod 94 is retracted as described above, occupies an abnormal position, as shown in broken lines. These levers are arranged to engage pins 112 upon the mal position.

levers 54 which retract the respective shuttleactuating plungers 51 at the opposite ends of the machine, and when shifted to the abnormal position as previously described by retraction of the rods 94, these arms 111 by engagement with said pins 112 shift the levers which carry said pins so as to retract the plungers 51, thereby preventing the shuttle from picking up a hair at the end of the stroke opposite that in which it orig-- inally failed in the pick-up operation. [is a result of this, the shuttle returns to the original position without functioning so far as the weft threads are concerned.

Return of the shuttle to its original posi tion without the hair would normally operate to lock the rod 94 at that end of the machine, which as previously described remained unlocked when the rod 94 at the opposite end of the machine was originally retracted. This, however, is undesirable in this instance, and in order to prevent it, ll provide at each end of the shaft 95 a second arm 113 which occupies a normal position, as shown in full lines in Fig. 7 and which when the rod 94 at either end of the machine is retracted as described is elevated to the position shown in broken lines. In this posi- 'tion,the arm 113 lies in alignment with a lever 114 pr itally secured to the lay at 115,

and operatively arranged with respect to the depending arm 89 which as previously described is adapted under certain conditions involving a failure of the shuttle to take up i a hair, to retract the rod 94 with which it cooperates by engaging the shoulder 93 on 'tllflli-llI'WELI'ClIIlOVQlllQIlt of the lay. The arrangement between the arm 113, the lever 114 and the arm 89 is such thatwith the arm 113 1n the elevated or abnormal position, the

lever 114 in the forward movement of the lay engages the curved extremity of the rod 113, see l ig. 5, and is rocked on its pivot so thatit engages the arm 89 and swings it out wardly to a position in which it fails to engage the shonlder93 on the rod 94. The lever 114 is frictionally retained in its rocked position by means of a spring 116 which closely confines the lever between itself and the fixed abutment 117 of the lay, the spring being carried by a belt 118 which also functions as the pivot pin for the lever. The lever 114 is returned to its original normal position at the next rearward movement of the lay by means of a cam-lit: arm 119 which is mounted in a position on the frame of the machineto engage the rear end of the lever 114 in such manner as to rock it into the nor- The arm 89 which when released returns to its normal depending position merely passes over and around the curved rearward side 121 of the member which provides the shoulder 93, as well shown in Fig. 5, and after passing said member again assumes said normal position.

In order to release the rod 94 at that end of the machine at which the shuttle originally failed to take up a hair, which rod was locked in the retracted position by the shoulder '98 as previously described, and to permit the shuttle to again take up a hair at that point for resumption of the normal loom operation, I provide a lever 122 at each end of the machine pivotally secured to the frame at 123 and operatively associated with a cam 124 upon a shaft 125 journaled in the frame and operated in synchronism with the movement of the lay and the other parts of theloom so as to malie one complete revolution for each full reciprocatory movement of the shuttle. The levers 122 are connected with their respective rods 94 by means of alienible connector 126 which passes over and around suitable pulleys 127, 127, the arrangement being such as indicated in Figs. 5, 7 and 18, that when the lever 122 is forced away from the shaft 125 by the cam 124, the rods 94 are moved sufficiently to release it from the retaining shoulder 98 and permit its moving to the normal advanced position. ll hen, therefore, in the present instance the shuttle returns to the position in which it originally failed to take up a hair, the pain 124 at that end of the machine functions to shift the lever 122 and thereby releases the rod 94 at that end of the machine, permitting the arm 101 to rock the shaft 95 and to return the rods 94 and associated parts to the normal position, leaving the machine in full normal operation.

During the idle movements of the shuttle, it is necessary, in order to maintain the design, to interrupt the operation ofthe jacquard mechanism, and for this purpose, 1. provide upon the shaft 95 an arm 128 which is connected by means of a flexible connector 129 with a lever 130 which controls the move ment of the design cards. These cards as is well known pass over a suitable spool 131 which is rotatably mounted upon a reciprocating structure (not shown), and the lever 139 carries a lug or abutment 132 which normally occupies a position in the path of the spool so that as the latter is moving in one direction and comes in contact with said lug, the spool is rotated through an angle of 90, thereby changing the cards. This spool is reciprocated and therefore turned in synchronisin with the moven'ient of the loom parts. The lever 130 is held in a normal elevated position by means of a spring 133,
